The General Assembly has passed legislation to require Illinois Department of Transportation (IDOT) road studies on traffic and environmental impact to be made public, which could potentially provide savings on local projects while improving transparency on state decisions.

House Bill 5138, sponsored by State Senator Jason Plummer, specifically requires that IDOT make public any study or survey that concerns traffic or the environmental impact of road construction projects.

The legislation passed the Senate on May 16 and now heads to the Governor.
